Rotate Array
You are given an integer array nums, rotate the array to the right by k steps, where k is non-negative.
Example 1:
Input: nums = [1,2,3,4,5,6,7,8], k = 4
Output: [5,6,7,8,1,2,3,4]Explanation:
rotate 1 steps to the right: [8,1,2,3,4,5,6,7]
rotate 2 steps to the right: [7,8,1,2,3,4,5,6]
rotate 3 steps to the right: [6,7,8,1,2,3,4,5]
rotate 4 steps to the right: [5,6,7,8,1,2,3,4]
Example 2:
Input: nums = [1000,2,4,-3], k = 2
Output: [4,-3,1000,2]Explanation:
rotate 1 steps to the right: [-3,1000,2,4]
rotate 2 steps to the right: [4,-3,1000,2]
Constraints:
1 <= nums.length <= 100,000-(2^31) <= nums[i] <= ((2^31)-1)0 <= k <= 100,000
